ejin4499 Posted August 26, 2015 Share Posted August 26, 2015 So I bought a 2006 pathfinder 4x4 se. It had the classic blown radiator but I got a good deal on it. I got the manual and the master rebuild kit and went to town. Gotta say a really fun project. Anyway the problem after the rebuild every gear shifts smooth as butter except 2nd. If I give it about 1/8 throttle it pops in like something rear ended me. If I give it 1/2 throttle it shifts relatively smooth but I can still feel it shift. I've read the manual and gone through the diagnostics as far as someone with out a consult can do. I'm not getting any light or dtc's. Is 2nd supposed to be hard under light throttle or do I need to start pulling parts and finding a way to bench test them? Or even better does someone have a consult 2 with obd2 adapter I can rent from them? Thanks guys Link to comment Share on other sites More sharing options...
ejin4499 Posted August 28, 2015 Author Share Posted August 28, 2015 no solution but may be valuable to someone sometime. http://www.gearsmagazine.com/magazine/view/801da54d-4fc7-4ff1-950e-46c757942748#page1 http://www.gearsmagazine.com/magazine/view/1e70aa21-c054-4e96-a301-3ae3ed420f35#page1 http://www.atraonline.com/gears/2007/2007-04/2007_04_40.pdf http://www.atraonline.com/gears/2010/2010-09/2010_9_36.pdf http://www.atraonline.com/gears/2010/2010-08/2010_8_16.pdf http://www.atraonline.com/gears/2010/2010-09/2010_9_4.pdf http://www.atraonline.com/gears/2007/2007-01/2007_01_12.pdf http://www.sonnax.com/articles/128-RE5R05A-Facts-and-Observations I think my answer may come from some of this information. If anyone looks at it and can tell me a procedure to try that would be great. I am not a mechanic I am just willing to teardown and transmission and rebuild it until I get it right.

ejin4499 Posted August 28, 2015 Author Share Posted August 28, 2015 ok so first thing that I'm going to try now that I have a diagram of pressure flow is jacking up the rear putting a gague on the direct clutch hydralic line and watching how the line pressure changes. As far as I know it should be a realatively smooth application of pressure. If its jerky I probably have a valve problem that needs looking at. If anyone would like to chime in here with any thoughts or brain farts that would be appriciated. Link to comment Share on other sites More sharing options...
